12ht stock will run 750c pre turbo, add more air (boost) or even better intercooled air, mine is 15psi in the inlet manifold, pump maxed out, 500-600 max pre turbine
If only this was the case, when the ring lands wear, then the rings break, often with very little indication, then they break into ever smaller pieces damaging the cylinder walls, getting past the other rings scoring the crank, blocking piston oilers open etc etc, I've seen it all to often, 2h...
Nice looking truck for sure
Imo any unopened 12ht or 2h past 300k needs to be torn down and alfin ring land pistons need installed, I've done a few and they all wear the ring lands and break rings, if you get them early enough, a hone and pistons and it's done.
Last one I did had to be sleeved...
12ht and 2h are different animals for sure, since going DI 12HT, 14psi manifold, extra 2.5 turns of fuel 3" thick intercooler directly in front of radiator and condenser, needle doesn't move from the bottom of normal in mr T's guage,
rest of cooling sytem is exactly the same as per 2h. could...
I can strongly advise anyone without around 350k+ (kilometres) to tear them down, and quick hone and piston/rings replacement with the alfin inserts, good for another 500k
fits with the standard airbox etc, later master cyl is longer and wouldn't fit, I used a later one to fab the adapter plate, as not to take the rig off the trail.
Cut the end off the input pushrod, cut thread on the rod to accept the standard clevis, shortened the master pushrod by 6.5mm, cut...
Works fine, is power box, not ram assist though
Although I should quantify that by saying the steering has never been good enough to effortlessly steer when locker is in, in tight gnarly situations. So am used to no power steer in these situations, brakes seem to be unfussed, as is first in the...
Installed a hydro boost out of an f250 over the weekend, 84 hj60, definitely a great upgrade, can lock the 35's at 60mph if desired. Should help hold it on those gnarly hills, where it always was a struggle to stop it rolling backward
